Well i have a custom ROM built by NFSFAN and it has a Internet sharing option that was in the post that you was referring to...all i have to do is connect via active sync then go to Internet sharing and turn it on...from this feature i have tethered with everything including my laptop,pc,and to go on xbox live...the link that i gave shows how to set up sharing via bluetooth which i set up only once and never used again after flashing the new ROM...

I'm pretty sure that most custom ROM's have this feature!!!
